Once a hybrid or upgraded turbo goes on and the car is living on ethanol, the standard cam-driven pump simply cannot keep the rail up, and every extra pound of boost costs the calibrator timing. The Big Bore flows 63% more fuel than the factory pump and carries a 240 bar rating, which is the highest of the EA888 pumps Nostrum builds for this engine. It is an all-welded stainless steel assembly and it ships as a full kit: pump, stainless high pressure tubes with OEM fittings, the electrical connector adapter harness, fitting hardware and an installation guide, so the fuel side of the job is covered in one box.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMk6 GTI builds on a hybrid or upgraded turbo where fuel is now the ceiling\u003c\/li\u003e\n\u003cli\u003eFull pump E85 running, where volume demand jumps sharply over petrol\u003c\/li\u003e\n\u003cli\u003eTrack and fast-road GTIs that hold high load for long periods rather than short pulls\u003c\/li\u003e\n\u003cli\u003eA build that is going the whole way and wants the pump chosen once, not twice\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhen A GTI Needs More Than The Standard Bore Pump\u003c\/h2\u003e\u003cp\u003eMost CCTA and CBFA cars are well served by the \u003ca href=\"\/products\/nostrum-2-0l-vw-ea888-ccta-cbfa-standard-bore-high-pressure-fuel-pump-kit\"\u003eStandard Bore kit\u003c\/a\u003e at 36% flow and 180 bar. The Big Bore is a different proposition: bigger displacement, a higher pressure ceiling, a Mk6 GTI-specific application.
